Before you make too many projections, check the USGS realtime earthquake maps and see the hundreds of tremors and small quakes that take place every year in the places you mention...
I agree with this statement...
So much of the predictions can be classified as "Chicken Little" thinking...Husker reakoning..
I happen to live about 5 miles inland from the Pacific Ocean (in the Eel River Delta) with a few dairy's in-between...a community within the Giant Redwoods...a community that thrives within numerous natural threats...
Directly west about another 5 miles or so is the terminus of the San Andreas Fault where it intersects the centroid of 3 continental plates...
About 25 to 30% of all California earthquakes eminate from that intersection...
Our elevation is exactly 50 feet above mean high tide...and we are about 1000 yards from the limits of the psunomi flood plain...
About 10 or so miles south is an area that has the highest rainfall in the United States...200 or so inches annually...
And yet surrounded by these threats, there is not one scientist that can predict how each of these elements will react...
As a child, my family traveled thru the Ozarks where I found a prediction-type novelty weather board that had a leather donkey tail...it said if the tail is wet, its raining; if the tail is white, its snowing, if you can't seee the tail, its foggy...thats as close to a creative prediction as it gets...
Making a worldly catastrophic prediction is like trying to catch a fart in the wind...
